ScienceClass 7CBSEAnswered 27 Mar 2026
Answer
Solution:
Transport of materials is necessary for both plants and animals as every cell needs a regular supply of nutrients and oxygen to release energy through respiration.
The food that we eat is broken down into smaller components to be absorbed by cells. The oxygen we inhale also has to be transported to all the cells of the body. Our body also requires the constant removal of waste materials such as carbon dioxide.
For the transport of all these materials (nutrients, oxygen and waste products), our body has a specialised transport system.
Similarly, in plants, the transport of water and food is accomplished with the help of vascular tissues (xylem and the phloem).
